Signals as small as 4m VPP can be amplified to drive devices with CML inputs. The SY88993V generates a chatter-free Loss of Signal (LOS) open collector TTL output. The SY88993V incorporates a programmble level detect function to identify when the input signal has been lost. This information can be fed back to the /EN input of the device to maintain stability under loss of signal conditions. Using LOSLVL pin the sensitivity of the level detect can be adjusted. The LOSLVL voltage can be set by connecting a resistor divider between VCC and VREF, Figure 2.
